丹參為常用的中藥,用於治療心臟疾病、活血袪瘀、調經止痛和涼血消炎等。從丹參甲醇抽取物之乙酸乙酯層中分離出六個丹參酮化合物acetyl danshenxinkun A (1) ,tanshinone IIA (2) ,1,2-dihydrotanshinone I (3) ,tanshinone I (4) ,cryptotanshinone (5) 及15,16-dihydrotanshinone I (6) 。其中acetyl danshenxinkun A (1) 為新化合物。這些化合物皆由各種光譜分析確定其結構。A new diterpenoid, acetyl danshenxinkun A (1), and five known tanshinones, tanshinone IIA (2), 1,2-dihydrotanshinone I (3), tanshinone I (4), cryptotanshinone (5), and 15,16-dihydrotanshinone I (6) were isolated from the roots of Salvia miltiorrhiza. Their structures were determined by spectroscopic methods. |
